TENSION-REGULATING DEVICE FOR LOOM-SHUTTLES.

SPECIFICATION forming part Of Letters Patent No. 447,629, dated March 3, 1891.

Application filed $eptember 11,1890. Serial No, 364,615. (No model.)

To all whom it may concern.-

Be it known that we, SQUIRE BENTLEY and ALFRED BENTLEY, both of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Tension- Regulat-ing Device for Loom -Shuttles, of which the following is a f ull, clear, and exact description. Our invention relates to improvements in tension-regulators for shuttles such as are used in weaving ribbons or other narrow ware. It is the common practice to regulate the tension of the silk, which is held on suitable quills in the ribbon-shuttles, by means of a back spring which presses against the silk upon the quill; but this pressure is uncertain, owing to the varying size of the quill as the silk is unwound, and consequently there are likely to be imperfections in the ribbons.

The object of our invention is to produce a tensionregulator of simple construction that may be applied to any variety of shuttle and that will hold the silk-quill with an even pressure without regard to the amount of silk thereon.

To this end our invention consists in a spring having one end fixed to the shuttlebody and having the opposite end coiled around the quill-spindle and arranged to press against one end of the quill. This construction will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying -in which the spindle O is mounted transversely, the ends of the spindle resting in suitable bearings in the shuttle-body on op posite sides of the opening (0 in the shuttlebody. The quill B ismounted loosely on the spindle O and the silk b thereon extends through a suitable eyelet D in the bow of the shuttle. The above construction is common to ribbon-shuttles and forms no part of our present invention.

The tension-regulator-E is formed of spring wire, one ende being doubled upon itself and inserted in the perforation a in the base of the shuttle A, and adjacent to the base of the shuttle the wire composing the regulator is coiled, as shown at e, to give it the requisite spring, and the inner end of the wire is formed into an eye e which loosely embraces the spindle G and presses against one end of the quill 13, thus forcing the opposite end of the quill against the side of the shuttle-body A and giving to it the necessary tension. The terminal eye '8 is arranged at right angles to the coil c, so that the coil will force the eye firmly against the end of the quill, and as the end 6 of the regulator which is inserted in the base of the shuttle-bodyis,doubled it effectually prevents the regulator from being twisted.

From the foregoing description it will be readily seen that the tension-regulator will exert an even pressure on the quill 13 without regard to the amount of silk thereon, and as a result the goods woven by means of the shuttle provided with the above regulator are much more perfect than when provided with the ordinary tension-spring.

The quill and spindle may be removed from the shuttle in the usual manner, and when they are again inserted the end of the spindle is thrust through the terminal eye 6 of the tension-regulator and then into its bearing in the shuttle.

Having thus fully described our invention, we claim as new and'desire to secure by Letters Patent 1. The combination, with the shuttle-body, of the spring tension-regulator having one end doubled upon itself and inserted in a perforation of the shuttle-body, having a central coil, as shown, and having a terminal eye inelosing' the quill spindle and pressing miual eye adapted to inelose a quill-spincl1e, against the end of the quill, substantially as substantially as described.
